Abstract
A method of forming a thin film transistor on a transparent plate. A silicon layer having an active area is provided. A first ion implantation is performed to form a deeper doped region in the silicon layer. A second ion implantation is performed to form a shallower doped region in part of the silicon layer. A transistor structure is formed on the silicon layer located at the active area. A glass plate is formed on the transistor structures. An annealing process whose temperature is about 200° C.˜600° C. is performed to peel the silicon layer from the deeper doped region and the shallower doped region, and to form a silicon thin film adhered to the transistor structure. Thus, the silicon thin film transistor can be formed on the glass plate without a high temperature process.
